On the parametric representation of univalent functions on the polydisc

Abstract

We consider support points of the class $S^0(\mathbb{D}^n)$ of normalized univalent mappings on the polydisc $\mathbb{D}^n$ with parametric representation and we prove sharp estimates for coefficients of degree 2.Comment: Minor corrections, references added.
